On Saturday morning, I went to pick up a 2 in. red severum from a local vendor about an hour away. I brought it home and acclimated it into the tank. When I finally added it, it was very shy, huddling in the corner or hiding in the flower pot or behind plants, which could be normal for a fish in a new tank. I monitored it all day/night and it seemed to be doing OK, coming out and swimming around a little more, but I noticed it swimming kind of without direction, occasionally swimming into the glass (not bashing into it but kind of running into it as if it didn't see it). I checked on it before I went to bed last night and it was hovering in the corner. This morning I found it floating at the top of the water dead. Naturally I checked all the water parameters and they are fine. Tankmates are a 4 inch turquoise severum, 4 giant danios, and 3 tiger barbs, none of which were bothering it that I saw.
My question is, what do you think could have caused this? My guess is stress but I don't really know what I could have done differently to lessen that. The fish was pricey and I am hesitant to purchase another one and have the same result, but it's a fish I've wanted for a long time. Could it just have been the individual fish? Any ideas or tips on what to do in the future to try to avoid this again?
